Introduction: Healthcare-associated urinary tract infections (HAUTIs) are among the most frequent nosocomial infections, and are a significant cause of morbidity, mortality, and healthcare resource utilization. The present study aims to describe the epidemiological and microbiological profiles of HAUTIs in third level medical facility in western Mexico. Materials and methods: A cross-sectional study was conducted using institutional data from 2025. Patients diagnosed with HAUTIs were included. Demographic, clinical, and microbiological variables, length of stay, catheterization duration, antimicrobial treatment, and susceptibility and resistance profiles were analyzed. Results: A total of 405 HAUTIs were identified. Most infections were associated with urinary catheters (75.8%). The average catheterization duration was 23.18 days, and the average hospital stay was 22.29 days. The main microorganisms isolated were Staphylococcus aureus (9.6%), Escherichia coli (9.1%), and Pseudomonas aeruginosa (8.6%). The highest resistance was observed against ceftazidime, ceftriaxone, and ciprofloxacin, while meropenem and imipenem showed the greatest susceptibility. Conclusion: HAUTIs continue to represent a significant disease burden, with a predominance of Gram-negative pathogens and high antimicrobial resistance profiles. Prolonged catheterization duration and hospital stay are relevant factors. Knowledge of local susceptibility profiles is essential to optimize antimicrobial therapy and strengthen prevention strategies.
